Abstract

The invention relates to a tert-phenol-furfuryl amine type benzoxazine monomer, cured resin, and a preparation method of copolymerized resin thereof. The preparation method includes: in a one-time feeding or stepwise feeding manner, an aldehyde compound, furfuryl amine and p-tert-butylphenol are added into a reaction container, and an organic solvent is added for dissolution; then the mixture is heated to 80-120 DEG C and subjected to stirring reaction for 6-48 h, and the reaction product is subjected to after treatment to obtain the tert-phenol-furfuryl amine type benzoxazine monomer; the benzoxazine monomer then is dissolved in the solvent, and the mixture is heated to be heat-cured, thus preparing the tert-phenol-furfuryl amine type benzoxazine resin; or the benzoxazine monomer is subjected to dissolution and blending and subjected to thermo-curing with a benzoxazine prepolymer to obtain benzoxazine copolymerized resin. The method is low in cost and simple in process, wherein the tert-phenol-furfuryl amine type benzoxazine resin and the copolymerized resin thereof have great thermal property and excellent dielectric performance, i.e., low dielectric constant and dielectric lossunder ultrahigh frequency. The product can be applied to the fields such as high-frequency and high-speed circuit board substrate, micron wave and millimeter wave communication, vehicle-borne radars,and other composite materials.

Description

technical field

[0001] The invention relates to the technical field of organic polymer materials, in particular to a preparation method of a tert-phenol-furfurylamine type benzoxazine monomer, a cured resin and a copolymerized resin thereof. Background technique

[0002] In recent years, the widespread use of electronic terminal products such as mobile phones and car navigation, especially the emergence of the fifth-generation mobile communication system (5G), marks the beginning of the comprehensive information age. In order to meet the requirements of high-quality information transmission, the communication is constantly developing towards higher frequency and higher speed, which puts forward higher requirements for the electronic components and their carriers - copper clad laminates, which require a very low and stable dielectric The dielectric constant (k) and dielectric loss (f), and the dielectric properties of the matrix resin play a key role in the dielectric propert...
